I wouldn't want any living or non-living thing put in orbit at this point except a space debris collector. So much shit in orbit that needs to be recycled or burned up. See: IMAX Space Junk or the anime Planetes.

Ultimate Bitcoin-powered hotspot. I'd pay to be able to work on getting a decent satellite ISP accepting BTC going. The draw to Bitcoin would be insane, and the satellite(s) could hold copies of the blockchain for relatively quick distribution. Too bad there's no cheap/easy way to make it immediately accessible to everyone like a WiFi hotspot. How cool would it be if you could just plug a USB dongle in and access 4+ different satellite hotspots?
